Equipotential Surfaces

The diagrams below show regions of equipotential. 

A positive charge is moved from to in each diagram. Choose the correct statement from the options given below:

1.	in all four cases, the work done is the same.
2.	minimum work is required to move in figure
3.	maximum work is required to move in figure
4.	maximum work is required to move in figure

The angle between the electric lines of force and the equipotential surface is:

1.		2.
3.		4.
